Influence of alpha and beta-adrenergic stimulators and blockers on the electroretinogram and visually evoked potentials of the rabbit.
The effect of alpha and beta-adrenergic stimulators and blockers on the electroretinogram and visually evoked potentials of the rabbit was studied. It has been observed that subcutaneous administration of noradrenaline, dihydroergotoxine, isoprenaline, propranolol and adrenaline influence the amplitudes of ERG and VEP waves. On the basis of the established results, the role of the adrenergic system in forming the bioelectric response of the retina and visual cortex is discussed.
